On May 12, 2026, Yongkang Shi, a jointly trained PhD researcher at Eastern Institute of Technology, Ningbo and Shanghai Jiao Tong University, successfully defended his dissertation, Hydroelastic Modelling and System Response of Flexible Offshore Floating Photovoltaic Systems in Complex Marine Environments.
The defense was held at Shanghai Jiao Tong University. Shi presented the research background, methodology, main results, and key innovations, and responded to questions from the examination committee. The committee approved the dissertation defense.
The dissertation addresses the trend toward larger, more flexible, and modular offshore floating photovoltaic systems, with emphasis on hydroelastic response in complex marine environments and analysis methods for large modular structures.
The work also considers combined wind-wave loading, complex connections, non-uniform wave fields, and the influence of structural motion on photovoltaic power performance, supporting dynamic-response analysis, safety assessment, and engineering design.
Shi's research focuses on hydroelastic response of offshore floating PV systems, coupled wind-wave dynamics, efficient modelling of large flexible floating structures, and photovoltaic performance assessment.
